ICE SKATE Filed Sept. 24, 1943 Patented July 4, 1944 UNITED STATESPATENT OFFI JOE SKATE Samuel Bloom, Dorchester, Mass. ApplicationSeptember 24, 1943, Serial No. 503,322 3 Claims. (01, 280-1112) Thisinvention relates to ice skates and more particularly to an improveddouble runner skate ments rigidly attached to the skate runners. Alsocooperating with the runners are oppositely threaded screws by which therunners can be conveniently adjusted. to desired widths from arelatively wide spacing suitable for young children to a close relationproviding a single runner for adults or more experienced skaters.

An important feature of my invention resides in the novel production ofthe guide elements from sheet metal strips bent U-shaped along theiredges to provide guiding troughs, the individual guides being merelypieces cut from said strips and attached to the base of the skate.

The base with the guides attached, together with the runners cooperatingtherewith, form the main body of the skate and the adjusting mechanismwhich I employ comprises simple oppositely threaded screw elements whichreadily combine with the base and runners when assembling these parts.The production of an improved skate embodying these novel featurescomprises a further object of the invention.

These and other features of the invention will be best understood andappreciated from the following description of a preferred embodimentthereof selected for purposes of' illustration and shown in theaccompanying drawing in which,

Fig. 1 is a side elevation of my improved skate;

Fig. 2 is a bottom plan view thereof with the two runners adjusted intocontact to provide a single runner skate;

Fig. 3 is a bottom plan view with the two runners adjusted to arelatively wide spacing to provide a double runner skate;

Fig. 4 illustrates one of the guides and the strip from which it is cut;v

Fig. 5 illustrates a key used in adjusting and gaugingthe runners;

a shoe. Secured to the bottom face of the base are threegu-ides l4, eachcomprising a piece cut from a metal strip l5 having its edges l6 bentoutwardly and inwardly .to U-shape and providing a guiding channeltherealong. The pieces are secured to the base In in such position thatthe channels extend transversely of the skate.

Each skate embodies a pair of runners I! each having rigidly securedthereto three supporting chairs l8 having guide portions 20 fittingwithin the channels of the guide members I4. The runners are adjustablealong the channels transversely of the skate and oppositely threadedscrew elements 22 are provided for thus adjusting the runnerssimultaneously in opposite directions. Two such elements are provided oneach skate, each element having oppositely threaded ends in threadedengagement with member 24 secured rigidly to the runners, and eachhaving a grooved intermediate portion 26 seated in the slot 28 of amember an secured rigidly to the base It. An

outer end of each threaded element 22 is squared at 32 for receiving arotating key 34. The key is also provided with spaced notches 36 adaptedto be applied as a gauge to the runners forthe purpose of equally'spacing the two runners throughout their lengths. I

It will be apparent that my improved skate is of rigid all-metalconstruction and can be manufactured at minimum economy, the severalparts being primarily of stamped sheet metal construction. The strips l5are easily and economically formed and the guiding elements M areproduced merely by cutting pieces from the strip and trimming the endsasshown in broken lines in Fig.4. These pieces can be welded or riveted tothe base In and the chairs [8 can be likewise secured to the runners. Inassembling the several parts the threaded elements 22 are dropped intothe slots 28 and the elements 30 threaded thereto as the guiding element20 pass into the guiding channels ofthe elements I 4.

Fig. 6 is a sectional view taken on line 6-.6

of Fig. 1.

The base In of my improved skate comprises a flat sheet metal stampingand is provided with Having thus described my invention what I claim asnew and desire tosecure the Letters Patent of the United States is:

1. An ice skate comprising a flat sheet metal base adapted to support ashoe onthe top face thereof, a plurality of sheet metal guides rigidlysecured to the bottom face of the base in spaced relation therealong andextending transversely thereof, a pair of runners each having aplurality of supporting elements rigidly secured thereto and slidablymounted in said guides, and a plurality.

of screws mnh havinn hxrn was! he Amman-n ners respectively and aportion intermediate the threads rotatably journaled against axialmovemerit on the base, rotation of the screws being adaptedsimultaneously toadjust the runners in opposite directions.

2. The skate defined in claim 1 wherein two of said guides are locatedrespectively beneath the toe and heel portions of the base and a thirdguide is located therebetween, and wherein two screws of opposite pitchare located respectively between the third guide and the other twoguides.

3. The skate defined in claim 1 in which said guides comprise metalstrips secured in face-toface contact with the bottom face of the baseand having their side edges bent outwardly and inwardly to provideguiding channels for receiving and guiding the runner supportingelements.
